WMV High Profile - possible syntax error?

I was just trying out the various file formats to get a rough idea of timings to strip commercials/encode to a different file format from a 6.8GB .ts hdhomerun connect file. The WMV seem to take 2+ hours, when I am less on the others – just thought this was an apparent error message that could contribute to the longer run. I will avoid the WMV as I thought I am doing better with my other samples:

MKV High – 1G/1h23m, MKV Normal – 829KB/38min, MKV Unprocessed 4.1GB/23min, MKV HEVC 1.6GB/1h20min. Once I decide on the format I wish to utilize, then I intend to set and forget. Thanks again.
